// A simple class to extend an abstract class and get loaded with different // loaders. This class is loaded via LOADER1. A similar named class will // be loaded via LOADER2. public class many_loader extends bug_21227 { public You_Have_Been_P0wned _p0wnee; // I need to compile (hence call in a loop) a function which returns a value // loaded from classloader other than the system one. The point of this // call is to give me an abstract 'hook' into a function loaded with a // foreign loader. // The original 'make(boolean)' returns a bug_21227. The VM will inject a // synthetic method to up-cast the returned 'from_loader1' into a // 'bug_21227'. public many_loader[] make( IFace iface ) { // This function needs to return a value known to be loaded from LOADER2. // Since I need to use a yet different loader, I need to make an unknown // foreign call. In this case I'll be using an interface to make the // unknown call, with but a single implementor so the compiler can do the // upcast statically. return iface==null ? null : iface.gen(); } }
